Answer:
45 applicants were selected to work in the international tennis tournament at your local stadium, but just 36 (Gemma included) completed all the training sessions.
Explanation:
1. Let's review the information provided to us to answer the question correctly:
Number of applicants to work in the international tennis tournament = 225
Number of successful applicants = 1/5 of 225
Number of successful applicants that couldn't make all the training sessions and were discounted = 20%
2. How many selected to work at the tournament?
For answering this question, we will make the following calculations:
Number of successful applicants = 1/5 of 225 (1/5 = 0.2)
Number of successful applicants = 225 * 0.2
Number of successful applicants = 45
Number of successful applicants that couldn't make all the training sessions and were discounted = 20% of 45
Number of successful applicants that couldn't make all the training sessions and were discounted = 0.2 * 45 = 9
45 applicants were selected to work in the international tennis tournament at your local stadium, but just 36 (Gemma included) completed all the training sessions.
